AUTOMATIC ALARM SIGNAL File g- 1928 2 Sheets-Sheet 2 v A T T Q R N EYPatented eh. 4, 1939 JOHN PELLONI, F ELI-WOOD CITY, PENNSYLVANIAAUTOMATIC ALARM SIGNAL Application filed August 22, 1928. Serial No.301,366.

This invention relates to alarm signal systems for use within dwellingsand the like for, signalling the presence of fire or the attempt athouse-breaking.

An object of the invention contemplates.

the provision of annunciators operable by bot-htemperature and contactwhereby fires and attempted burglaries may be detected.

Another object of the invention comprehends an operating mechanismwhereby the receiver upon a telephone may be lifted, a phonographstarted and a bell rung whereby the occupant of the house and the firechief may be notified of the fire. More specifically stated theoperating mechanism is provided with a holding element whereby thedevice may be supported while being reset.

With the above and other objects in view, the invention further consistsin the following novel features and details of construction, to behereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claim.

In the drawings Figure 1 is a vertical sectional view taken through myinvention.

Figure 2 is a top plan. view of the phonograph and telephone.

30 Figure 3 is a detail sectional view taken through the operatingmechanism.

Referring to the drawings in detail, wherein like characters ofreference denote corresponding parts, the reference character 10indicates a cabinet within which a phonograph 11 and telephone 12 aresupported. The speaker 13 for thephonograph is adapted to face thetelephone transmitter 14, the purpose of such arrangement will bepresently apparent.

The operating mechanism includes a cylinder 15 having a bottom 16 andwithin which a plunger or piston 17 is mounted for reciproeating action.The plunger or piston shaft 18, upstanding from the piston, is projectedwithin the core 19 of a solenoid coil 20.

A fusible element 21, preferably stretched across the ceiling or wall ofa room or a series of rooms, is passed over a pulley wheel 21' andextended within an opening 22 in the solenoid coil 20 for connectionwith a ring 23 upon the free end of the plunger shaft 18. Sucharrangement normally supports a piston or plunger 17 to occupy theposition shown in Figure 1 of the drawing.

A cable 24, having connection with the upper side of the plunger orpiston 17, is passed over pulleys 25 and 26 whereby the same may bedisposed directly above the telephone receiver 27, whereby the cablewhen connected to therewith will. effectively lift the receiver when thepiston is lowered. By the same token, the cable 28, also havingconnection with the piston 17 and passed over the pulley wheel 25 and aseparate pulley 29, is connected with a switch, arm 30 for thephonograph 11, whereby the telephone receiver 27 and phonograph 11 willbe simultaneously set in motion. The record upon the phonograph isadapted to inform the fire and police chiefs of the burning of thefusible element by reason of the fact that the telephone transmitter 14faces the speaker 13 but it may also be desirous to inform the occupantsof the house as well, and in this instance an tor in the nature of abell 31 is employed.

Said bell is adapted for connection in circuit with a step-downtransformer 32 through the instrumentality of a conducting wire 33,whereas its opposite pole is connected with a 8 switch member 34-through a lead 35. The switch 34 is in turn connected with a stationaryportion 36 of a knife switch 37 through a conducting wire 38. The knife37 is adapted for direct connection with the transformer 35 32through awire 39. Obviously the transformer is energized from the house currentand this is accomplished through cables 40 and 41 respectively. Thewires 38 and 39 respectively are in turn connected with wires 42 and 43having connection with contact members upon window frames which whenbrought into contacting engagement by the raising of a window will ringthe bell 31 irrespective of the presence of the knife switch 37.

A spring latch finger 44, operating within a sleeve member 45, is adated for connection at its uppermost end with a cable member 46 passedover pulleys 47 and 48 respecber 52.

tively for subsequent connection with the upper side of the piston orplunger 17 in oppositely disposed relation to that of the cables againstby a retractile spring 49.

When the occupants of the house leave, for any purpose, the switch 34:may be opened to break the circuit between a stationary portion of theknife switch and the bell, whereby the latter will be renderedinefiective and the burglar will not he scared off.

After the fusible element 21 has been hrokon by the temperature createdby a fire, the plunger or piston 17 will drop and actuate thephonograph, phone, and bell.

After the stylus arm for the phonograph has traveled a given distanceacross the record therefor, a contact member 51 carried thereby isadapted to engage a contact mem- The contact 51, carrying a lead wire53, is adapted for connection with a contact member 5a located in thepath of movement of an osciliating head 55. The other contact 52 carriesa lead wire 56 which is connected to one side of the step-downtransformer 32 to a lead wire 5'? and the house current. The head iscarried shaft 58 able in housing 59 con: the cy nder A lead wire ihetween the head 55 A push button o ected in circuit with the lead l thehouse current, is adapted to as solenoid cod 6?) whereby the core refermay be actuated simultaneously in conjunction with a shaft member 64:having connection with the shaft member 58 for the head 55 through theinstrumentality'ot' an arm 65. The shaft member 64 is in additionadapted for connection at its free end h a knife switch 3?.

The invention is susceptible of various changes in its form, proportionsand minor details of construction, and the right is herein reserved tomake such changes as properly fall within the scope of the appendedclaim.

Having described the invention, what is claimed is 1-- An apparatus ofthe character described comprising a normally inoperative phonograph, anormally inactive telephone arranged to dispose the transmitter thereforin juxtaposition to the speaker of the phonograph, a cylinder, a weightmember slidahly mounted within the cylinder having operative connectionwith a telephone receiver and phonograph brake to efi'ect simultaneousoperation thereof, a solenoid disposed adjacent said weight, a plungershaft for the weight slidably arranged within the core of the solenoid,a local annunciator, a switch member located adjacent and normall heldin open circuit with the annunciator y the Weight, a shaft membercarried by and extended through the cylinder for frictional engagementwith the adjacent surface of the weight member therein, a contactincluded upon the shaft member in oppositely disposed relation to thatof the weight, a stationary contact arranged in the path of movement orand normally frictionally engaging the contact upon the shaft member,and spaced contacts included upon the phonograph and tone arm thereforbeing designed for ultimate contacting engagement to retract the weightmember, brake the phonograph and replace the telephone receiversubsequent to the phonetic and annunciator signals.

in testimony whereof ii afiix my signature.
